Lolobau volcano (left) sits astride the western rim of a caldera that formed about 12,000 years ago on the 8 x 13 km, oval-shaped Lolobau Island. It is seen here from the south across Expectation Strait along the NE coast of New Britain. The peak at the right lies on the eastern rim of the 6-km-wide caldera. Several vents within the caldera, occupying an E-W-trending line on the eastern flank of Mount Lolobau, have been active during historical time.

The oval-shaped island of Lolobau lies just off the northern coast of New Britain, west of Cape Deschamp. Lolobau was constructed over the western rim of a 6-km-wide caldera. Eruptive activity from vents on the flank of Lolobau inside the caldera have continued into the 20th century.

Lolobau volcano (left center) sits astride the western rim of a 6-km-wide caldera, which formed about 12,000 years ago on the 8 x 13 km, oval-shaped Lolobau Island. Lolobau is seen here from the south beyond the lower flanks of Ulawun volcano. The smaller peak at the right is located along the eastern caldera rim. Several vents within the caldera along an E-W-trending line on the eastern flank of Mount Lolobau have been active during historical time. The latest eruptions took place during the early-20th century.
